money earning trick

OK, I was kinda sick for the last 2-3 days, and that's why I haven't posted any new tricks (and why my previous trick wasn't so good). I will try to find you the newest and coolest tricks around, and not only the card ones. That's why with this trick, you will not only do magic, but can also earn you some money (depending on your victim's sense of humor and intelligence). All you need is some money, a friend with more money and a container/box (an empty box of matches will do just fine). Put 20$ (or any other amount, but don't push it) in a box, then ask your friend to give you the same amount of money which you will put in the box too. Now start telling him how there are $40 in the box and what can a man do with them...in other words: keep yapping . Now ask him if he would like to buy the box for a bargain of $30. If you played your part good, he won't suspect a thing and he will buy it. Now thank him, pack the money and get going...you just made $10. Just don't expect any favors from the guy in a while.
